循环宇宙由于幻影和精髓

Cyclic universe due to phantom and quintessence

Changjun Gao, Youjun Lu, You-Gen Shen

摘要:

我们探索一个循环的宇宙由于幻影和精髓领域。我们发现,在宇宙演化的每一个周期中,幻影支配着宇宙的早期历史,而精华支配着宇宙的遥远未来。在这个宇宙模型中,有无限的膨胀和收缩循环。与暴胀宇宙不同,对应的宇宙时空是测地完备的,是量子稳定的。但类似于循环模型,宇宙的平坦性问题、视界问题和大尺度结构都可以在这个循环宇宙中得到解释。

英文摘要:

We explore a cyclic universe due to phantom and quintessence fields. We find that, in every cycle of the evolution of the universe, the phantom dominates the cosmic early history and quintessence dominates the cosmic far future. In this model of universe, there are infinite cycles of expansion and contraction. Different from the inflationary universe, the corresponding cosmic space-time is geodesically complete and quantum stable. But similar to the Cyclic Model, the flatness problem, the horizon problem and the large scale structure of the universe can be explained in this cyclic universe.
